The earbuds are priced at around $26 during their initial sale in China, making them a more budget-friendly option compared to the Oppo Enco Air 5, which costs $29.
The Enco Air4s support active noise cancellation (ANC) of up to 32dB, which can reduce everyday sounds including conversations, traffic, and background music.
For users who need to stay aware of their surroundings, a transparency mode is available, allowing them to hear their environment without removing the earbuds.
The earbuds use two microphones combined with AI algorithms to reduce surrounding noise and improve voice clarity during calls, making them ideal for use in noisy environments.
Battery life is a key feature of the Enco Air4s, with up to 12 hours of playback per charge when ANC is turned off. This drops to around eight hours when either ANC or transparency mode is enabled.
With the charging case, total playback reaches up to 43 hours, providing users with a long-lasting solution for their listening needs.
Oppo claims a 10-minute charge provides up to four hours of listening time, ensuring users can quickly recharge their earbuds when needed.
The earbuds have received TÜV Rheinland certification, which guarantees consistent performance after 1,000 charging cycles.
The Enco Air4s carry an IP55 rating for dust and water resistance, making them durable and suitable for various environments.
During testing, the charging case survived falls from 1.5 meters, while the earbuds were tested from 1.8 meters, showcasing their robustness.
